Ultra LSX 750W Power Supply Review

Closer Look:

The smooth satin black finish to the Ultra LSX 750W power supply will show fingerprints and scratch easily, but it still looks the part.

The rear face of the power supply shows the IEC mains input connector, large mains on/off rocker switch, and the exhaust grill, which fully utilizes all the remaining space. The cable exit port is lined with a plastic grommet to prevent damage to the cables, which are fully sleeved all the way into the power supply.

Nothing much to see on the side panels apart from the ventilation grills, which will introduce a little warm air back into the enclosure.

The bottom face of the power supply carries a comprehensive specification label along with 80 Plus, ATI Crossfire X, NVIDIA SLI Ready, and lifetime warranty logos, as well as a selection of production/test stickers. The large 135mm black cooling fan is covered with a black wire grill bearing a black and silver Ultra LSX logo at its center.

The Ultra LSX 750W isn’t modular, which means the cable set looks a little messy. However, with a little thought and careful cable management, this shouldn’t prove too much of a problem in all but the smallest of enclosures. The black mesh sleeving is secured with cable ties and heat shrink, which should keep things in place.

The 135mm cooling fan bears the Ultra brand, but the DFS132512H model number suggests it is manufactured by Young Ling Tech and part of its 12V high speed range. The printed circuit board is neatly laid out and uses a combination of solid state and 105 °C electrolytic capacitors.

The two vertically mounted DC to DC convertors shown in the photographs for the 3V3 and 5V rails are becoming more and more popular and are no doubt part of the drive for higher efficiencies. The cable entry points onto the printed circuit board are particularly tidy, which shows a certain level of care at the build stage. I couldn't find any information on the printed circuit board that pointed toward a particular manufacturer, but the E239028 number points toward Andyson International being the OEM.

The Ultra LSX 750W power supply is well packaged with a good set of accessories. The build quality is on a par with other power supplies in its class and the black printed circuit board appears well built. Let’s move on and see how well it performs.
